Example 4.1: Creating a Time-Based Greeting

In this example, we will check the current time and then display an appropriate greeting based on the time of day.

      </HEAD> 

      <BODY> 
      <!--- Check if it is morning or afternoon and customize greeting 
              Use the Now() function to get the current Date and time 
              Use the Hour() function to isolate just the hour

        <H2> 
        <CFIF Hour(Now()) LT 12> 
            Good morning,
